PASTRY-FEEDING MECHANISM FOR PASTRY-CONE MACHINES.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed'Jnly 10, 1919. Serial No. 309,852.

To all whom it may concern: 7

Be it known that 1, CHARLES F. Bn'rz, a citizen of the United States, and residing at St. Louis, Missouri, have invented the new and useful Improvement in Pastry- Feeding Mechanism for Pastry-Gone Machines, of which the following is a specification. p v

This invention relates to pastry or batter feeding mechanism, and more particularly to mechanism adapted to feed pastry or battel to the baking devices .or molds of a baking machine, such as a'pastry cone machine. r

In the manufacture of baked products, such as pastry cones, the machine comprises atraveling frame having a series of molds thereon with which cooperates a series of cores. The pastry or batterissupplied to the molds by means ofa suitable feeding mechanism, while the cores are separated from and clear of the molds and the cores then enter the molds and press the batter or pastry to shape and pass-into an oven where the molds andthebatter therein are heated to bake the latter and form the baked product or article;-the mold is then opened by separating the cores therefrom and the baked product is withdrawn.

In such a machine, the molds and cores should be heated and remain heated uniformly; in view of the fact however, that the molds must pass close to and underneath the 7 batter outlets of the feeding mechanism, this mechanism is subjected to the radiant and convective heat from the molds; the result is, therefore, that the batter is liable to coagulate to some extent, stopping the outlets and clogging the entire mechanism so that the operation of the ma chine is not "only interfered with but may This is particularly disadvantageous in a machine for mak ing pastry cones for in such a 'machine the batter must be measured with accuracy, especially in View of the small amount of batter really contained in a pastry cone.

' Oneof the objects of this invention, therefore, is to provide mechanism whereby the batter may be fed accurately to the baking device and whereby the feeding mechanism is so constructed and arranged and has such provisions as to insure the reliable operation thereof.

Further objects will appear from the detail description taken in connection with the accompanying drawing in which Figure l is a vertical section of a pastry cone machine and showing the pastry or batter feeding mechanism embodying this invention; 7 I

Fig. 2 is adetail side elevation showing the operating cam; and i Fig. 3 is a section on the line 3-3, Fig. 1'.

Referring to the accompanying drawing, land 5 designate standards or supports and 17 designates a traveling'frame showinga track 18 resting on a series of rolls 19 mounted in the standards 5. The traveling frame 17 has a toothed flange 21 coeperating with a pinion 22 on a shaft 23 mounted in the standard'a so as to impart a rotary movement to the traveling frame 17. The traveling'frame has mounted thereon a series of baking devices comprising sets of molds and cores, the molds 24 having cone shaped mold cavities 25 which cooperate with cores 26 mounted on core supports 27 in turn pivotally mounted on the traveling frame so as to'be movable into and out of the molds. A series of heating pipes il mounted on standard 5 apply flames to the bottom of the molds traveling thereover and there is a series of heating pipes applying flame to the upper faces of the core supports when the cores are in position in the molds. This mechanism is fully shown and described in application Serial Number 309,851 filed of even date herewith.

A batter receptacle 45 is mounted on an overhanging bracket 46 on the standard 4 sofas to place the batter receptacle over the molds in the traveling frame. Batter is fed to this receptacle or cylinder by a conduit from an overhead tank (not shown) so as to supply batter to the receptacle by gravity and a valve 56 is provided to cut oil the supply of batter.

. A'piston 57 travels in the cylinder or receptacle 4:5 and this piston is mounted on a piston rod l7 adjustably mounted on one end of a lever 48 pivoted intermediate its ends on the bracket 46 and having its other end adj ustably connected with a rod 49 hava part of from the main ing at its free end a cam roll engaginga cam on a sprocket 51 driven by a chain 109 drive shaft as described in the application referred to. The piston has a cup packing 58 of leather or other suitable material which is clamped between the piston body and a plate 59. V

The batter receptacle l5has a partition which is formed to make guides for a pair 7 52 and below this partition of valve stems which forms a false bottom is a space 61. Passing through this space 61 is a series of perforated nipples 62 which are screwed into the valve guides, and the partition above the valves is perforated at 63 to alinewith the perforations in the nipples. The valves are provided with perforations 64: adapted to aline the perforations 63 with the nipples when the valves are open. The valve stems 52 are connected by a cross-head-65 in turn connected with a shank 66 which is slotted at its end and takes over theend of one arm of a bell crank lever 53,. the other arm of which hasa cam roll engaging a cam5 lon the sprocket 51. A setscrew 67 is provided to furnish a proper bearing between the shank 66 and the bell crank lever 53. The space6l which has below the outlet valve,connections1 68 which may be flexible connections-taking over nipples 69 on the receptacle body and connecting with the water jacket.- During the operation of the m sprocket feeding mechanism and the traveling frame will be operated in timed relation. Assum ing that a set of molds is opposite the feeding mechanism sothat the mold cavities 25 in a set will be opposite the nipples 62 and that the cores 26 are at this time out'of the moldas shown in Fig.

through the'bell crank and shank connec 'tions heretofore described move the valve 'to connect the outlet nipples 62 with stems 52 to the right (Fig. 1) so as to aline the perforations 63 and the nipples in order the interior of the receptacle. As this is done the cam 50 will through the shank and lever connections heretofore described move the piston down a predetermined amount there'- I by forcing predetermined quantities of batter through the valves and into the mold cavities; the valve stems 52 are then again moved to the right thereby cutting .off the outlets; the piston will then again be moved up, thereby drawing another quantity of batter from the supply tank through the pipe 55. This operation is repeated whenever a set of -molds comes Iunderneathlfthe batter feeding mechanism.

. It will be seen that when a set of molds is I underneath the batter feeding mechanism, the batter feeding mechanism including its outlets, the valves, the batter receptacle and forms a water jacket V achine the 51 being connected to the pinion 22 batteroutlet therefor, anda cooling j aeket is operated in timed relation so that the.

'1, the cam 54 willlation of the c'ooling' 'waterin" the cooling j' cket shields the entire mechanism against the heat from the molds so that no coagulation will takeplace and the operation is not impaired. Accordingly, it is. not only pos sible to use simple feeding mechanismbut it is also possible .to use a simplecup packing on the plston; alljof which is of great ad; Vantage in, the handlingof a peculiarly obstinate material such as batter. in a hot 7 machine. v a 7 It is obvious thatvarious changes may be made in the details of construction without departing from the spirit ofthis invention; it is, therefore, to be understood that this invention is not tov be limited to the specific construction shown and described.
